Get ready for one of the most iconic hikes in Glacier National Park. A big part of the trail follows a broad path, but as soon as we reach Ptarmigan Lake, the views open up and we can see the thin ridge trail snaking toward the tunnel. A solid climb awaits there. But then you'll reach the historic tunnel. Stepping through this hand-carved passage is something. It’s a truly dramatic reveal that makes you feel like you’ve discovered a hidden world. The tunnel feels like a teleport that carries you from one breathtaking landscape straight into another. On the far side, you might overlook Elizabeth Lake, where the scenery might be even more beautiful.
